We report a pump–probe experiment revealing the temporal evolution of subpicosecond evolution of Prodan's excited‐state absorption in dimethylformamide. Also, we present calculation of the first spectral moment of this spectral band and estimation of different relaxation components on the subpicosecond time scale.
